Abstract

A method and associated system for controlling valve timing of a turbine engine, the method may include: classifying a plurality of control regions according to engine load and engine speed; in a first control region, applying a maximum duration to the process valve and control the valve overlap between the exhaust and intake valves; in the second control region, maintain the maximum duration of the intake valve; in the third control region, close the intake valve timing and exhaust The valve closing timing is advanced; in the fourth control region, the intake valve closing timing is controlled to be close to bottom dead center; in the fifth control region, the throttle valve is fully opened and the exhaust valve opening timing is retarded; and In the six control regions, the throttle valve is fully opened and the intake valve closing timing is controlled to prevent knocking.

Description

[0001] Cross-references to related applications [0002] This application claims priority from Korean Patent Application No. 10-2015-0177482 filed on December 11, 2015, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a system and method for controlling valve timing of a continuously variable valve duration engine. More particularly, it relates to a system and method for controlling valve timing of a continuously variable valve duration engine by installing a continuously variable valve duration device on an intake port in a turbine engine and continuously variable The variable valve duration device and the continuously variable valve timing device are installed on the exhaust port to simultaneously control the duration and timing of the continuously variable valve. Background technique [0004] The internal combustion engine burns a mixture of fuel and air in a predetermined ratio ...
